Obediah Bias West Virginia

I have another ancestor in WV from the Civil War: Anthony Armstrong Bias on my paternal grandmothers side trace here: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=33892516... His son Roland "Ro" Bias was my great grandfather. It is reported his ancestor Obediah Bias from WV fought in the American Revolution but I have not been able to verify. I would love more info on this so I could have a Patriot on my dads side too! If you have any info on that please let me know.
